# FreeUsername

> Free username search at https://freeusername.com/. Type one username (or up to five) and the tool checks 3,450+ public websites in 10 categories, live, and labels each one Found, Not found, Blocked or Unknown. Found results can show the public display name, avatar and bio. Results export as JSON or CSV. No sign-up. The site shows ads to stay free; searched usernames are never shared with advertisers. The username is sent to our server only to run the check and is not stored or logged.

FreeUsername (domain: freeusername.com) is an independent tool. It is not affiliated with or endorsed by the WhatsMyName project, Sherlock, Maigret or any site it checks, and it is a different site from look-alike domains with similar names. The website and Android app use WhatsMyName data (CC BY-SA 4.0) with Sherlock and Maigret, credited on the site and in the app; its own engine adds more sites it verifies itself. It searches by username only: not by real name, phone number or address. It is not a people-search site or a consumer reporting agency and must not be used for FCRA purposes (employment, housing, credit, insurance).

## Facts

- Price: free. No account, no API, no CLI
- A Found result is a lead to verify, not proof that one person owns an account
- Android app: FreeUsername: Username Checker (our own partner app, same engine): https://play.google.com/store/apps/details?id=whatsmyname.app.us
